This invention is directed to improve ments in bearing construction and has for its general object the provision of a resiliently mounted bearing adapted'to support a rotatab le member such as an axle or shaft.

A further object of my invention isthe provision of an economical resiliently mounted bearing construction adaptable for use in supporting the shaft of a toy vehicle having a resiliently mounted body;

Other objects 'of my invention will herein-= after be set forth in the following descrip tion which refers to the accompanying drawings illustrating a' preferred form thereof. The essential characteristics are summarized in the claims.

In-the drawing, Fig; 1 isa plan view of my hearing construction mounted upon a leaf spring of a vehicle; Fig. 2 is a side elevation of the bearing construction and 3 is a cross-sectional elevation taken substantially along the'line 3-3 of Fig. 2. My invention contemplates the provision of a resilient means in-the nature of a cushion for a tubular journal comprising a bearing for a rotatable member such as a shaft. As shown in the drawings, a bearing journal 10 may be mounted upon a block 11 comprising both a bearing bracket and a cushion for the journal sleeve whereby any unalignment of a bearing journal 10, by reason of a deflecting movement of the supporting spring leaf 12, will permit the journal member to align with the journal member of a similar bearing mounted on an other leaf spring, not shown. Theblock 11 may be formed of an suitable resilient material preferably a bi whereby the journal maybe cast in the block when the rubber is being molded and cured. If desired theblock may be bored andthe journal inserted in the bore, the bore being of less' diameter than the journal whereby it may be prevented from endwise move rises a U-shaped member 16 having-the ent portion-thereof seating in a oove 20 formed' in the upper portion of t e block.

- journal sleeve,

resilient The legs 17 thereof extending through openings in the block which are aligned with openings formed in the spring 12 whereby-nuts 18 may engage the protrudingends of the legs of the member 16 to secure the block to the spring. The journal member 10 may have the inner bearing surface 1 thereof suitablbyuslotted as shownat 23. The slot may be ed with graphite or other anti-friction substance whereby the bearing is self-lubricating'thus eliminating the ne-' cessity for the use of oil which would be detrimental to the life of the resilient block 11.

* It will be understood that the block may be formed of other material than rubber and may be of a shape other than the one shown in the drawings, the particular shape shown being chosen merely for convenience in illustratmn, and adaptation to a leaf Havlng thus described my mvention, I claim: V 1. .In combination a leaf spring for a vehicle, an axle and a sleeve bearing directly engaging the same to support it, and means for supporting the sleeve to allow a weaving movement between the spring and the axle,

comprising a block of resilient material in which the sleeve is embedded, and means penetrating the block on either side of the sleeve and spaced apart from the-sleeve by said resilient material and arranged to clamp) the block flat against the spring.

2. n combination a rotatable member, a a supporting member for the sleeve comprising a rubber block having a wide base and a U-shaped member engaging the moldedirubber member exteriorly thereof above the bloclg the legs of the U-shaped member extending through the rubber and enga ing the supporting member.-

3; combination arotatable member, a bearing therefor comprising a journal sleeve, having the bearing surface intersticed with anti-friction material filling the interstices, means supportin the sleeve comprising aock 0 material having a wide base and means extending around the sleeve and through the block for securing the bearing to a su porting means.

4. A sha t bearing comprlsing a bracket formed of resilient material-and having a central body portion, a substantially flat base and outwardly extending flange portions, the bod portion having apontinuous a. base, and. a sleeve embedded in the body groove exten ing over the top and sides portion adapted to receive and directly supthereof, and the flanges h'avmg through port a, shaft. openings in registration with the ends of In testimony whereof, I'hereunto affix my 5 the groove, a U-shaped member extendin signature. 4

along the groove and into the openin an' 4 having means for clamping the brac et to JAMES M. HOWE.
